This diagram shows a typical surface cross section as it might appear, magnified many thousands of times, under an electron microscope. The surface might be that of a fiber, or of a painted wall, or even wall paper. In Line No. 1, rough soil...
This scene at the Newburgh, New York plant shows a step in the manufacture of coated fabrics. This illustration shows what is known as jig dyeing. The base goods are dyed to a shade closely approximating the face color of the finished goods....
Certain types of coated fabrics require a soft or fleece back. Notable among these are those designed for table covers and upholstery fabrics. This photograph shows the operation where the nap or fleece back is completed at the Newburg, New York...
Here is how a fabric processed with a water repellent will react toward globules of water. Not only is the design attractive in itself but it clearly shows the practicability of a water repellent treatment. Material processed with DuPont Aridex or...

This illustration shows a step in the manufacture of DuPont fabrics, at the Newburgh, New York plant. The scene is that of the coating head of the machine where many even coats of composition are spread and driven into the weave of a cotton base...
Operation of a calendar capable of turning out millions of yards of plastic coated fabric a year may be controlled form this central instrument board at the Newburgh, New York plant of the DuPont Company's Fabrics and Finishes Department. The...
Section of calendar, capable of turning out millions of yards of plastic coated fabrics a year at the Newburgh plant in New York. This calendar, which weighs 175 tons was placed in operation in 1957.
Standard spray testing equipment used to determine the water repellency of a Zelan treated fabric versus an untreated fabric in the DuPont Technical Laboratory, Fine Chemicals Division, Deepwater, New Jersey.
Recently designed and constructed by the DuPont Chemicals division is this new 'Raintester' which duplicates the effect of rain on garments and fabrics and makes it possible to measure their water repellent qualities. By adjusting the nozzle at the...
Textile chemicals to make cotton and rayon resist creasing and mildew are aims of research by DuPont chemist shown here drying treated samples in this laboratory at the Experimental Station. Textile chemical research stems from early work on dyes.
Better goods satisfy customers and build markets. Quality tests during the development of a new pigment are charted above in a laboratory of the DuPont Company. DuPont carries on extensive research, both applied and fundamental.
This picture shows some fabrics tested at a DuPont laboratory. Untreated, an undyed piece of tent fabric (second from left) shows rich growth of mold after 21 days contact with culture. Piece in center, treated, was protected.
This is a test strip of carpet, portions of which have been treated with Ludox collodial silica. After vacuuming, treated areas emerge clean, while untreated portions remain dirty and dingy.
This is the newest type of multiple testing machine which examines all finished pyroxylin coated fabrics for resistance to abrasion at the Newburg, New York plant.
Testing for color fastness with heat and ultra violet radiation are made by the fade-o-meter on pyroxylin coated fabrics at the Newburgh, New York plant. Seventy-two hours of the exposure in the fade-o-meter are equivalent to about two years of...
